Craftsman 12 gal, 2.5 HP compressor bogs on startup
System builds up to 80 PSI and I shut it off manually. On trying restart the motor bogs down as if it is bucking the load within the tank. Im guessing its the check valve. Please advise.
craftsman 30 gal 6 horsepower blows breakers
i was using it the other day and when i was using it it was suposed to kick on and fill back up with air but it didnt so i went over to see what was wrong with it and realized the breaker was kicked off so i put it back on and plugged it in and it turned on and 3 seconds later it kicked off again any tips? please help me?
First thing to do is turn it off, drain all the air from the tank, close the drain valve again, and turn it on.
Does is start and run, or does it kick off the breaker? Post your response as a comment here please so I can follow our discussion.
older craftsman 12 gallon air compressor ~ Reset button pops upon re-filling tank
Not sure if this is the right area, But i have an older craftsman 12 gallon air compressor that i got for free, that for some reason, Plug it in and it will run and fill to correct pressure and then cut off.
Then, as you're using it, When it drops below pressure, It goes to re-start, lights dim, motor turns (slower then normal) will go maybe 5 rotations and then click, reset button on motor clicks off.
Push reset button, same thing.
Drain all air from tank, hit reset starts up fine and runs and fills tank to capacity.
(Yes, unload valve is releasing air, i hear the hiss)
OR, If i plug it in (from 0 psi), and let it fill to any pressure, pull the plug, press unloader valve (hear the hiss), and go to plug it back in, Same deal. turns over few times then off.
Things i have already tried, new cord, checked pump, checked stopper valve (I think thats what it is, The one way valve going from compressor to tank)
What could be wrong??
I dont think its the motor, why would it be able to run no problem at 0 psi-120psi, but anything past 0 on startup it cant?
I've been getting very frustrated with this compressor and don't know what to do.
So far I'm only into it $12 bucks for a new belt and a lot of aggravating hours of work.
Its a 1hp motor belt driven to a two piston pump.
Any help would be great!
Glad to help, if I can, and I too wish I had some BigMoney!
Here's what I think. You have a pretty good power circuit to your compressor, and you don't have a lot of other electrical "stuff" interfering with getting a good current flow to your compressor.
Your current flow is soooooo good, that even though most electric motors need an electrical boost to start, yours is able to pull enough power from the supply circuit to start when there is no load.
However, add some load (pressure in the system makes the motor work harder) and the motor needs more amperage on start up, and your system isn't providing that.
I think that if you check your motor capacitor, that will be your problem. The capacitor is what is supposed to give your electric motor the boost it needs on start up. Without the capacitor adding the boost, your motor pulls too many amps, and pops the breaker.
Craftsman 6HP 33 gal unit compressor blows fuse
I have a 7 year old Craftsman 6HP 33 gal unit that worked fine until the other day.
The compressor will run for about 2 seconds then blow the fuse.
I disconnected the feed lines to the tank and get the same result.
Being the motor spins it doesn't appear to be siezed. What other tricks can I try before I junk it?
You removed the line from the pump to the tank, and that should have unloaded the piston. If the tank isn't empty of air, reattach the line, and dump the tank air anyway, and try to start it again.
I'm suspecting a start capacitor issue, but I need you to rule out the unloader valve first.
